Best for: A pint-sized track-styled sportbike built for spirited backroad riding, carving corners, commuting, and learning proper sport riding skills.
Built for: A miniature superbike with real GP-inspired attitude - eager, revvy single that must be worked hard, delivering big-bike thrills at modest speeds.
Not ideal for: Not for those wanting outright speed, relaxed touring comfort, two-up practicality, off-road use, or a laid-back upright commuter.
